MACHINE FOR COATING BISCUITS OR OTHER ARTICLES WITH SUGAR, CHOCOLATE, OR SIMILAR ICING.

SPECIFICATION forming part of Letters Patent No, 791,363, dated. May 30, 1905.

Application filed October 3, 1904. Serial No. 227,041.

To all "whom it may concern:

Be it known that .I, H nRMANN Pnonnn, manufacturer, a subjectof the Prince of Lippe, residing at Detmold, in the Principality of Lippe, German Empire, have invented certain new and useful Improvements in or Relating to Machines for Coating Biscuits or other Articles with Sugar, Chocolate, or Similar Icing, of which the following is a specification.

My invention relates to improvements in or relating to machines for coating biscuits and other articles with sugar, chocolate, or other materials.

The object of the invention aims to provide a machine for coating biscuits or other articles with sugar, chocolate, or other material, particularly adapted for coating perforated articles, as well as overcoming the objection of the soiling of the conveyer for the coated articles, as in the machines now in general use. The part of the machine which dips the artiticles also transfers the articles as well as turns the articles over onto and upon the conveyor. It is furthermore found impossible to dip the articles several times in succession when employing machines now in general use and obtain a uniform spreading of the coating material upon the articles, and such objection is overcome by the machine hereinafter described.

The known machines which are suitable for treatin biscuits or other articles (hereinafter called articles) of any size, thickness, and shape are generally so complicated and so difi'icult to handle that they have not been or are but very little used.

The above drawbacks are avoided by my invention, which is distinguished by being capable of dealing with articles of any desired shape and size. The articles are introduced in rows into the compartments of a grateshaped transport-frame moving forward and backward to the extent of the width of one row on a fixed support and also moving up and down, which frame pushes the articles in rows onto a perforated frame rising and descending at suitable moments and dipping into the icing, from which frame the work after having been dipped one or more times is pushed off onto a dcpositor or turn-over rack, which again deposits the dipped work with its covered surface upward on the transport-band.

A construction of that part of the machine according to this invention which contains its new parts is illustrated in the accompanying drawings, in which Figure 1 is a side elevation; Fig. 2, a plan with the transport or carrier frame partly broken off; Fig. 3, a vertical cross-section, and Fig. 4 a vertical longitudinal section, all these figures showing the apparatus diagrammatically. Figs. 5 to 8 are detail views, and Figs. 9 to 11 show a modified construction of the transport frame or grating.

The articles are delivered from the wellknown transport band or chain provided with compartments arranged in rows onto an oblique chute 2, corresponding to the said compartments. In order to cause the articles to retain the position given to them, the chute in question, which is a piece of sheet metal, is provided with transverse ribs 3, corresponding to the cross-ribs of the carrier-chain links or with the ribs of the compartment row of the same. The chute 2 is mounted on a table L, and on the said table there moves a carrier-frame 5, divided into rows of compartments 6. The compartments 6 correspond to those of the chute 2 and the carrierchain 1. The transport-frame 5 executes a for ward and a backward movement to the width of about one row of compartments, said movement being produced by a transverse spindle 7 of the machine by means of cams 8, arranged at both sides of the machine. The cams 8 act on slide-rollers 9, mounted on the shorter arms of two spring or weight controlled double levers 11, projecting upward and pivoted at 10 to the machine-frame. The upper ends of the levers are fork-shaped and loosely ongage the pins 12, arranged on both sides of the transport-frame 5. Besides itshorizontal reciprocating movements the transport-frame 5 also executes avertical reciprocatingmovement approximately to the extentof its height, and for that purpose it rests with lateral angle-pieces 13 loosely on rails 14 and is vertically guided in the frame. The rails 14 are provided with downward arms 15, guided on the frame and carrying at the lower ends rollers 16. These rollers are operated by cams 17, mounted on the cross-spindle 7. IVhen the carrier-frame 5 occupies its left and lowest position in Fig. 4 and its left frame-wall 18 is directly under the chute 2, the articles will be discharged into the left row of compartments of the transport-frame 5 and rest on the table 4. When the transport-frame 5 moves toward the right, the articles contained in the left row of compartments of the same are moved forward by its left wall 18 to the extent of the width of one compartment on the table 4. Then the frame 5 rises during its return to its left position in order not to take the articles back again to their former places on the table and in order again to seize and move forward the next articles which after its return and descent have fallen from the next carrier-chain link over the chute 2 on the table 4. All the compartments of the carrierframe 5 having been so provided with articles in the way described the first row of articles on the table 4 reaches at the next movement of the carrier-frame 5 the dipping-frame 22, arranged directly over the reservoir 21, containing sugar, chocolate, or any icing. This dipping-frame is divided into one, two, or more rows and is perforated or made in the shape of a grating. It merely reciprocates vertically, and to that end it is carried by the arms 23, mounted on the transverse bar 24. In order to render the motion of the dippingframe 22 independent of that of the carrierframe 5, the arms 23 pass loosely through slots 49 of the lateral flanges 13 of the carrier-frame 5. (See Figs. 2 and 3.) The crossbar 24 is guided in vertical slots 25 of the frame 26. The free ends of the bar 24 carry the arms 27, projecting downward and arranged outside the frame 26, which are guided vertically in projections 28 of the frame 26.

The lower ends of the arms of the clippingframe 27 are mounted with rollers 29 and are raised by cams 30 of the spindle 31, so that the dipping-frame 22 is moved up and down by its own weight at equal intervals, whereby the articles on the frame are dipped with their lower surface into the icing contained in the reservoir 21.

The right frame-wall 32 of the transportframe 5 is flush with the left frame-wall 33 of the first row of compartments on the dippingframe 22, so that during the advance of the transport frame 5 the dipped articles are pushed off onto a grate-shaped depositing device (depositor) 35, which can be turned through an angle of about one hundred and eighty degrees by means of a spindle 34. After the articles have been pushed on the depositor the depositor 35 is operated and lies during this act in same plane with the completely-raised dipping-frame 22. (See Fig.

4.) The depositor places the articles with their iced surface upward onto another transport-band 36 and conveys the same to any desired place. The movement of the depositor 35 is effected at the proper time by one of the arms 27. To that end one arm 27 is provided with two projections 37 and 38, an arm 39 of a toothed segment 41, rotatably supported on the frame at 40, engaging between said projections. This toothed segment 41 engages with a pinion 42, mounted on one end of the depositor-spindle 34. During the upward and downward stroke of the arm 27 the projections 37 and 38 alternately press the arm 39 of the toothed segment 41, and in this way the depositor 35 is alternately placed opposite the dipping-frame 22 or opposite the transportbancl 36. An arm 50, mounted on the spindle 34, secures the end positions of the turning device.

In the construction illustrated the dippingframe 22 has two rows of compartments. The articles are therefore dipped twice. If it is desired to dip the work more than twice, it is necessary to provide the dipping-frame 22 with more rows of compartments.

In the construction described it can happen, owing to the different shapes of the articles, that they do not fall properly from the transport-band 1 over the oblique chute 2 into the transport-frame 5. To avoid this, the apparatus can be constructed as shown in Figs. 9, 10, and 11. The oblique chute 2 and the springfingers 19 are done away with and the upper carrying portion of the transport-band 1 is placed in the same horizontal plane as the transport-table 4. In this construction the falling of the articles is avoided and the articles are moved from the transport-band 1 directly t0 the table 4 by means of the transport-frame 5. The wall 18 of the transportframe 5 may have teeth 43 on the lower side, which will pass in between teeth of the transport-band, securing a positive grip of the arti cles without damaging them.
